A charge air cooling assembly in which water pressurized by air at reduced pressure from the air brake system of a vehicle powered by a two or four cycle Diesel engine is discharged intermittently as a spray into the intake or discharge of a turbo-compressor, in response to the demand pressure on the intake manifold of an engine to lower the rate of fuel consumption of the latter and increase the torque and power output of the engine.

In an automotive vehicle powered by an internal combustion engine that has a turbine driven compressor that withdraws air from the ambient atmosphere and discharges said air at an elevated pressure to an intake manifold, said vehicle including a pressurized air actuated brake system and a battery, the improvement for intermittently increasing the density of air flowing to said intake manifold by cooling the same, said improvement comprising: a. a reservoir that defines a confined space for storing water, said reservoir having a water outlet; b. a normally closed, spring loaded, solenoid operated valve that has an inlet and an outlet; c. a normally open pressure switch responsive to the pressure in said intake manifold, said switch closing when a predetermined pressure is reached in said intake manifold; d. first means for pressuring said confined space with air from said air brake system to force pressurized water from said outlet; e. second means for injecting pressurized water from said reservoir into air from said compressor prior to said air flowing to said intake manifold; f. conduit means that connect said water outlet to said inlet of said solenoid operated valve and said outlet of said solenoid operated valve to said second means; and g. an electrical circuit connected to said battery, said electrical circuit including said pressure switch and solenoid operated valve, said pressure switch when said predetermined pressure is reached assuming a closed position to electrically energize said solenoid operated valve to move to an open position whereupon pressurized water flows to said second means to cool said air flowing to said intake manifold, with said flow of pressurized water continuing only so long as the pressure in said intake manifold is at least said predetermined pressure.
